Question 965070
Place a decimal point between the first two nonzero digits: 2 and 8


2.8


now count how many spots you need to move the decimal point to the right to get back to the original number. You need to move 10 times


So that means *[Tex \LARGE 28,000,000,000 = 2.8 \times 10^{10}] (notice how the exponent is 10, which represents how many times you move the decimal point)
